This family of acyl-CoA ligases includes Bacillus subtilis YhfT, as well as long-chain fatty acid-CoA ligase VraA, all of which are as yet to be characterized. These proteins belong to the adenylate-forming enzymes which catalyze an ATP-dependent two-step reaction to first activate a carboxylate substrate as an adenylate and then transfer the carboxylate to the pantetheine group of either coenzyme A or an acyl-carrier protein. The active site of the domain is located at the interface of a large N-terminal subdomain and a smaller C-terminal subdomain
